Berry Gumbolt - Northstar
Berry Gumbolt is a fully opaque saturated dark blue. It is well suited for stringer application and blown work. It is not susceptible to reduction and is not flame sensitive. For best results keep it in a neutral flame. It is a great backing for such colors as NS014 Irrid and NS015 Turquesa, and goes well with NS063 Canary.
Second quality glass can have the properties of odd quality glass, but may also have small stones, air bubbles, vary in tone/shade, or the shape can be very out of round. Both odd and second quality glass can provide a great value to the right person.

An under-appreciated gem!

This is an awesome background/base for any frit that's super-saturated with metals, because it's "reactive" -- Berry Gumbolt itself doesn't change colors, but it somehow grabs the fume from other colors, making a hazy halo around each speck of, say, Aurora or Amazon Bronze. For even more awesomeness, after you've melted your frit in (and played with spot-oxidizing or reducing), encase with a light transparent like Ice Blue, Sublime, or GA Cobalt Lite.
Great saturated blue. I use it for seahawk fans
